...I did my first intentional canopy stall at about 15 jumps. To get an A licence in Australia, you need to complete a canopy handling table, which includes static & dynamic stall recovery.

Congrats, Dave. I'm sure there's someone out there who has done it in less jumps - not good IMHO. I would not recommend everybody doing so at 15 jumps. I am part of the "slower progression" school of thought.

.If properly briefed...

I think that has already been addressed with several comments about "talk to your instructor." 15 jumps is not a magical number for anyone to start anything. It is an indicator of inexperience, though.

You will get a more definitive answer from Brian Germain, if that's what you are looking for.
